So after the first season, what perennial underplanting do you recommend? I understand the concept you're describing, but remember this is an isolated raised bed, not a food forest system.
I built a raised bed for 2 blackberries and a raspberry (all thornless). The bed is about 10' by 3'. Right now the soil is mulched but I'm looking for ideas for a companion/underplanting/groundcover. Strawberries? Perennial herbs?
Thanks!
